2. (22pt- Turn in HERE ) Eric is considering different distributions for the variable x. He takes a few samples to try to get an idea. For each of the following distributions nd: A. the probability of getting exactly 4, B. the probability of getting at least 4, 'C. the probability of getting more than 4, D. the average and standard deviation of each, {you may need to investigate another formula or two) E. the probability to getting an average of at least 4 with a sample of 25. Distributions: |.|. X~Nl5, 3.5) lll. x~U(1, 9) IV. X~B(8, 0.2) He thinks the average should be around 3 and the standard deviation around 2.71. Which one would you say is the closest? Why
